Finger vein module DEWO embedded finger vein reader
The DFV100 vein identification module is a high-performance processor with a finger vein recognition algorithm based on the company's proprietary intellectual property rights. It has intelligent veins with functions such as vein entry, comparison, and search and feature template storage without the participation of the host computer. Identify the module. This module is suitable for identity authentication, such as access control, attendance, safe, door lock and other high security and low power requirements. T

1. Autonomous algorithm: efficient and accurate vein recognition algorithm, recognition speed < 1s (100 samples), rejection rate (FRR)
< 0.01%, false rate (FAR) < 0.0001%;
2. High safety: the characteristics of the veins are concealed and in vivo;
3. Ultra-low power consumption: finger touch sensing, static power consumption < 10uA, dynamic power consumption < 100mA;
4. Easy to develop: It can communicate with the module through serial port or USB, and it can facilitate secondary development with each command protocol.
Compared with fingerprint and face recognition, vein recognition is safer because veins are under the skin and are not easy to be copied or stolen. Therefore, vein recognition is mainly used for high-security scene authentication, such as banking systems, payment systems, medical industry, deep integration of the Internet of Things, access control systems, etc.
